This invention relates to a gate hinge. It has for its main objects toprovide a hinge that will be highly satisfactory for the purposeintended, simple in structure, cheap to manufacture, easy to install,and extremely durable. Its dominating feature is that it provides meansfor mounting a gate in such a way that it will be adapted for beingpushed open by an automobile and will automatically close after the carhas passed through and cleared the gate.

Other objects and advantages will appear from the drawings anddescription.

By referring generally to the drawings, a part of this application, itwill be observed that Fig. l is a top plan view of a gate equipped witha hinge according to the present invention; Fig. 2 is an elevationalview of the complete gate with hinge thereon; Fig. 3 is an elevationalview of a part of the gate showing the hinge partly open; Fig. 4 is atop plan view of Fig. 6, with the gate frame member in broken lines,showing the position of the top portion of the hinge when the gate isclosed; Fig. 5 is a view similar to Fig. 4 but showing the hinge partlyopen; Fig. 6 is a detail view showing the hinge parts separated andpositioned with the gate closed; Fig. 7 is a view on line 77 of Fig. 4showing the hinge parts separated [and positioned with the gate 90degrees open]; Fig. 8 shows the hinge closed with the gate closed; Fig.9 is an elevational view of the hinge closed with the gate closed; andFig. 10 is a view on line 1010 of Fig. 5 showing the hinge partly openon part of the supporting post and the foundation thereof.

Similar reference numerals refer to similar parts throughout the severalviews.

Referring to the drawings in detail it will be seen that the hingecomprises three parts, 1 that is attached to the supporting post 2 by abolt 3, and is provided with integral abutting portions or lugs 4, andpart 5 that is also provided with abutting portions or lugs 4, with part5 adapted to partly revolve around the post 2, and part 6 that is alsoprovided with integral portions or lugs 4, with part 6 attached to thegate frame member 7, and adapted to partly revolve around the post 2.The upper hinge member 8 is a ring around the gate post 2 and is adaptedto slide upward and downward as the gate is opened and closed. I

From the foregoing it will appear that when the gate is pushed open byan automobile moving against the board 9 on the gate, the top part ofthe hinge will revolve with the gate causing its integral lugs to makecontact with the upper lugs on the freely revolvable member of the hingeto carry it around till its lower lugs make contact with the lugs on thebottom member of the hinge at which time the gate will be approximaely135 degrees open. Then when the gate becomes free of obstruction it willautomatically swing back to its closed position as a result of gravityforcing the hinge parts to their closed position.

'ice

The latch 10 of the gate will release the gate inward and outward as thedownward extending portion of the gate part slides upon and off of thepost part and is retained in a centered position by the slant structureof the hinge. The hinge will operate in the same manner when the gateispushed open from either side and will swing to positions inward andoutward to approximately the same degrees from the closed position.Latch 10 comprises collars secured on post 2 and member 7 and providedwith interengaging portions which are disengaged when the gate is swunginwardly and elevated, and also outwardly as the hinge structure isidentical for both movements as plainly shown in Figs. 6 to- 10inclusive.

The various parts of the hinge may be made of any material suitable forthe purpose, but we prefer to use metal pipe or the like. Also theparts'may be made in different sizes and capacities, depending on the size ofthe gates on which to be used.

While we have shown and described the preferred embodiment of ourinvention, we do not wish to limit same to the exact and precise detailsof structure, but reserve the right to make all modifications andchanges so long as they remain within the scope of the invention and thefollowing claims.

Having described our invention we claim:

1. A gate hinge of the character described comprising, a piece of metalpipe with one end cut straight across and designated the lower end, theupper end cut to form two opposite V-shapes, a lug. attached to theouter face of the upper pointed portions of each V-shaped portion, around metal pipe supporting post, said piece of pipe being adapted to beattached to the bottom portion of the supporting post, with the upperpoints of the Vs at right angles to a plane perpendicular to the face ofa gate supported on said post; a second piece of pipe cut to formV-shapes in both of its ends with the outer edges of the Vs beingparallel with each other and of a size to fit adjacent the Vs in thesaid first member of the hinge, a lug attached to the outer end portionof the upper end of each V on said second hinge member and a lugattached to the lower outer end portions of each V on said second hingemember; a third piece of pipe with one end cut straight across anddesignated as the upper end, the lower end thereof being cut to form twoopposite V-shapes of a size to fit in the Vs of the second piece, a lugattached to each lower outer face portion of each V of said third pieceof pipe, said upper third piece being attached to the frame of the gatewith the lower points of its Vs in line with the plane of the gate; saidlugs on the upper third piece adapted to make contact with the upperlugs on the second piece and the lower lugs on the second piece adaptedto make contact with the lugs on the first piece when the gate is movedinward or outward from its closed position. I

2. For use as a gate supporting and gravity closing hinge, a pair ofsleeves disposed for mounting one above the other about a verticallydisposed post, the upper sleeve being rotatable and slidable on the postand adapted for attachment to the gate and the lower sleeve beingadapted for attachment to the post, on intermediate sleeve rotatable andslidable on the post between the said upper and lower sleeves, coactinginterengaging cam surfaces on adjacent ends of said sleeves urging thegate toward closed position upon rotation of the upper and intermediatesleeves, and coacting means on said sleeves limiting relative rotationtherebetween to the extent that said respective cam surfaces remain insaid co-acting interengaging relationship, said coacting means includinga stop member on each of said sleeves normally circumferentially spacedfrom and engaging a stop member on an adjoining sleeve during relativerotation of said sleeves whereby rotation of said upper sleeve with thegate will turn said intermediate sleeve until its stop member engagesthe stop member on the lower sleeve.

3. For use as a supporting and gravity closing hinge for a gate, upper,lower and intermediate pipe-like hinge members, the adjacent ends ofeach of said members having thereon V-shaped cam surfaces whichrotatably engage complementarily formed V-shaped cam surfaces on theother members, said upper member being adapted for attachment to thegate and the lower member being adapted for attachment to a gate post,and a stop on each of said members engageable with a stop on an adjacentmember and effective to limit relative rotation of said members andthereby maintain said respective V-shaped cam surfaces in engagement,whereby upon opening the gate the upper and intermediate members rotatesuccessively in that order relative to the lower member and when rotatedurge the gate toward closed position.
